/**
 * @file
 * Script to invoke project_issue periodic code outside of hook_cron().
 *
 * On some sites, hook_cron() becomes very busy and you can frequently get
 * timeouts where all of the cron-tasks can't be completed during the time
 * limit for web-based PHP requests. To aleviate this problem, you can move
 * some of the code invoked by hook_cron() into separate CLI scripts which you
 * invoke directly by adding additional entries to the crontab on your system.
 * If you do this, you must also set the "project_issue_hook_cron" variable
 * to FALSE in your site's settings.php file.
